STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 400,202, dated March 26, 1889.

Application filed November 5, 1888. Serial No. 290,068. (No model.)

'0 aZZ whom it may concern.-

lie it known that l, AUGUST FISCHER, aciti m. of the United States, residing at \Viniester, in the county of Scott and State of linois, have invented certain new and useful nprovements in Stem \Vinding and Setting i atches, of which the following is a descripi011.

This invention relates to stem winding .vatches.

The invention consists in the construction and combination of parts by which the wind ing-bar is retained in its various operative positions.

Figure 1 is a section and partial elevation of part of the outer rim of a watch, showing gravitycatch in proximity to the win ding-bar, the winding-bar being in its inner position. Fig. 2 is a similar view with winding-bar in its outer position. Figs. and 4 are similar views showing gravitycatch at one side only of winding-bar. Fig. 5 is a face view of gravitycatch, Fig. 1, and Fig. (3 an elevation of wind lug-bar with head in section.

A indicates the outer rim of a watch-case. This rim has a recess near the pendant D for the reception of a gravity-catch, 15. The pendant and rim have the usual passage for the winding bar or pin C. Fins or stops A A in the rim. limit the movement of the gravitycatch 13. The bar or pin t carries gears F G, one of which engages a wind in g-gear, ll, when the bar (I is in its outer position, the other engaging the setting-wheel I when the pin is pressed inward, at the same time disengaging the winding-gear, as is common in winding mechanism of this class. The bar or pin has a milled head, C, and a spring, S, in arecess in the pendant bears against this head to push it outward. The pin or bar 0 has one or more grooves, C or other inequalities with which. the gravity-catch B may engage in certain positions.

The gravity-catch .13 is preferably a thin plate of metal, curved lengthwise to conform to the recess in the rim, and having the sides rounded to form bcaring-surfaces. The catch preferably has a perforation, l3, shaped like a keyhole, through which the pin or bar 0 passes, as shown in Figs. 1 and \Vith this construction the normal position of the bar C is shown in Fig. 1, the bar or pin (1 passing through the small end of the key-hole slot. In this position the watch may be turned over; but the catch 1-3 will be held from sliding by the bar C. The watch is then in position for winding.

For setting the hands, the bar is pressed inward and the watch turned in such position that the gravity-catch 1-3 will slide downward, the narrow slot of the passage B then embracing the grooved part C of bar C. Then on releasing the pressure from the button of pin C said pin will be held by the catch B from any longitudinal movement, but maybe turned to operate the setting-gear. By holding in the pin and turning the watch over the pin may be released.

Fig. 4 shows a gravity-slide which engages the groove at only one side of the winding-bar. Fig. 3 shows still another form of gravity-catch. It is apparent there may be many forms.

I claim 1. The conibinai ion, with the sliding winding-barof a stem-winding watch, of agravitycatch in the ease in position to engage and hold said baragainst longitudinal movement, substantially as described.

2. The combiimtion, with the winding-bar of a stem-wimling watch and a spring bearing the same outward, of a sliding gravity-catch in the casing, and stops to limit the movement of said catch, substantially as stated.

3. The combination, with the grooved winding-bar of a Stem-winding watch, of a sliding gravity-catch having a perforation through which said bar passes. said perforation being of unequal width, so as to embrace and hold the grooved portion of the bar when in one position, as set forth.
